Compré mi despensa en línea (usando la página de un centro comercial) y en total por los productos que adquirí debía pagar $1600
Mekhanik [1.2K]

Answer:

1.235%

Step-by-step explanation:

Paso 1

Calculamos el costo de envío

= $ 1620 - $ 1600

= $ 20

Paso 2

¿Cuál es el porcentaje de mi compra que me cobraron por los gastos de envío?

Esto se calcula como:

(Costo de envío / Cargos totales) × 100

= 20/1620 × 100

= 1.2345679012%

= Aproximadamente = 1.235%
